DESCRIPTION

The OPA832 is a low-power, high-speed, fixed-gain

amplifier designed to operate on a single +3.3V or +5V

supply. Operation on ±5V or +10V supplies is also supported.

The input range extends below ground and to

within 1V of the positive supply. Using complementary

common-emitter outputs provides an output swing to

within 30mV of ground and 130mV of the positive supply.

The high output drive current and low differential

gain and phase errors also make it ideal for single-supply

consumer video products.

Low distortion operation is ensured by the high gain

bandwidth product (200MHz) and slew rate (850V/μs),

making the OPA832 an ideal input buffer stage to 3V

and 5V CMOS converters. Unlike other low-power,

single-supply amplifiers, distortion performance improves

as the signal swing is decreased. A low 9.3nV/√

Hz input voltage noise supports wide dynamic range operation.

The OPA832 is available in an industry-standard SO-8

package. The OPA832 is also available in an ultra-small

SOT23-5 package. For gains other than +1, −1, or +2,

consider using the OPA830.
